In general no. Please do not try to assume you will be able to get

please code the full algorithm, and skip those nodes there. You will avoid
wasting a lot of time on design, coding, testing and when your users

just white spaces is hard so what ???
thanks for your hints. Ok, you convince me easily, of course i want to
write proper code without any assumptions that at some point break my code.
Also, as an inbetween solution i tried to iterate over the document (already
loaded) and remove those parts that are text nodes that just contain
It seems to me that having a loop over some node->children and removing
some of them in that same loop is somehow not a good idea, at least glibc
aborts my program due to double-freeing memory. So i had to program it
I don't see why this should not work
I really can't debug your code, no time for this, but I can give the follwing
advice: don't use isspace() for XML code as this is locale dependant and if
suddently someone run your code with a different locale the behaviour will be
different and you really don't want that !
Test the characters code points instead
